Summary
This Nodal Protocol Revision Request (NPRR) clarifies that the Current Operating Plan (COP) High Sustained Limit (HSL) for Load Resources controlled by high-set under-frequency relay should be equal to their expected power consumption. In Real-Time telemetry the HSL should equal their consumption. ERCOT can calculate the value for the additional available capacity from Load Resources controlled by high-set under frequency relays with a Responsive Reserve (RRS) Ancillary Service Resource Responsibility from (COP HSL – COP LSL – COP RRS). This value can be used in place of the COP value for additional available capacity from NPRR698, Clarifications to NPRR595, RRS Load Resource Treatment In ORDC.
